Answer
a. Moment of B =
b. Moment of A =
c. Weight of A =
To find the exact weight of A, we need the distance from the pivot for both A and B. If the distances are equal, then Weight of A = 50 pounds. If not, use the formula in (c) with the given distances.
Explanation
This problem involves understanding the concept of moments in physics, specifically the principle of moments (or torque) for a lever in equilibrium. The moment is calculated as the product of the force (weight) and the distance from the pivot. For the lever to be balanced, the moments on both sides must be equal.
